I own a XPS 1730 and just bought a new slimdrive UJ 220 BluRay drive and swapped it out with my DVD/RW drive. I can see the data on the disk but none of my programs will play the BR movie! I have CyberLink PowerDVD8 which will play blu-rays so it's not that. Any input, PLEASE? It's driving me crazy trying to figure it out...
